Preheat the oven to 180°C (fan oven). This is 200°C for conventional ovens (or 400°F / gas mark 6).
Place the halved sprouts into a bowl and drizzle over the olive oil, garlic powder and salt. Mix well until all the sprouts are evenly coated.
Spread them out onto a roasting tray and place in the oven for 20-25 minutes, rotating and shaking the tray halfway through.
Scatter grated Parmesan over the roasted Brussels sprouts and serve immediately.
